Long <br />Division Dneaor <br />RE: Powderhorn oar Co any 1997 Annual Subsidence Report <br />( r o: C-81-041) <br />I have reviewed the 1997 annual subsidence report submitted by Powderhorn Coal Company <br />for its Roadside/Cameo mining complex. The approved permit requires the conduct of twice <br />yearly visual inspections of the potentially effected area above the Roadside South and <br />Roadside North mines. Several previously documented cracks were observed to be continuing <br />to infill and "heal". No phenomena were observed which did not comply with projections <br />included within the permit subsidence predictions. <br />Once again, Mr. Larry M. Reschke, P.E., has prepared the most illustrative subsidence visual <br />monitoring report I've reviewed in the past year. <br />cc: Larry Routten <br />Doc: C:\WP51\COAL\POW97SUB.WPD <br />JP/p <br />
